Figure 9.13 Stator flux estimation based on scalar product correction method [8]

The only machine parameter required in the estimator is stator resistance The winding resistance is not constant but varies with temperature. The resistance value affects signal entering at the input of low-pass filter. When the magnitude of applied voltage very low, which is the case at lower speeds, the error in stator resistance creates significant error in the flux estimation. Thus, although simple, accurate and robust at higher stator frequency, the voltage-model-based flux estimators suffer due to two main problems: the integration problem at low frequencies and sensitivity to stator resistance variation.
